CustomVue with IR Technology
|Advanced Custom Laser Vision Correction
Bansal Eye Hospital is proud to introduce the cutting edge the Wavescan Technology along with Star 4 Laser with Iris Registration to provide you the very best in laser vision correction.
The VISX STAR 4 Advanced CustomVue System with IRIS Registration provides several unparalled advantages:
|Distinct tailoring for Personal Best Vision.
|Iris Registration Technology
Iris Registration Technology is a non-contact method of aligning the treatment to the cornea that provides greater laser alignment accuracy. IR technology replaces manual, ink-based methods of treatment alignment. This technology not only identifies the exact location of the iris but also rotates the laser treatment to match any iris rotation that may have occurred during LASIK.
|The Key Patient Benefits of VISX Iris Registration Technology:
It’s normal for the pupil to shift positions from the point of wavefront measurement to the point of treatment.
Accurate alignment is essential to optimizing customized wavefront-guided ablations, and the VISX Iris Registration Technology makes it easer than ever with a fully automated method.
When the CustomVue procedure is performed, the Iris Registration Technology hospitals the treatment correctly, independent of changes in the pupil hospital from measurement to treatment.
|How does VISX Iris Registration Technology work?
One set of measurements are taken with the patient seated at the WaveScanT, and another set taken with the patient lying down on the laser bed. Then, the technology employs a five-step iris registration process:
The system maps the iris.
The system then selects prominent reference points for each iris.
Using a set of sophisticated algorithms, the system finds multiple matching reference points for each iris.
The system then calculates the treatment surface angles from multiple matching reference points.
|The Advanced CustomVue treatment also features:
Variable Spot Scanning. (VSST)
Variable Repetition Rate. (VRRT)
Tissue sparing algorithms.
Fast treatment times.
Minimal temperature changes.
3-D ActiveTrakT with auto hospitaling.
VISX Star S4 Laser System
Together, the WaveScan WaveFront System and STAR S4 Excimer Laser System at Grewal Eye Institute deliver unprecedented levels of measurement accuracy and outstanding treatment precision essential to the Advanced CustomVue procedure. VISX has worked to target and optimize four essential steps to maximize the effectiveness of wavefront driven treatments.
Microscopic bits of tissue are removed with each laser pulse with the total treatment on the eye amounting to less than the width of a human hair. This reshaping is designed to correct vision problems.
The digital information from the WaveScanT System is transferred electronically to the STAR S4 IRT Excimer Laser System which performs the CustomVueT procedure.
The vision in the IntraLase-treated eye was preferred 3-to-1(among those who stated a preference).
